“条件”的质量或体型测量对于生态学和进化的研究至关重要，人们通常认为条件测量的差异与健康呈正相关和线性相关。通过引用生态学研究中的例子，我们发现，健康状况的指数通常不太可能与健康状况呈线性关系。研究人员需要更明确地承认基于大众的条件测量的局限性，并承认在某些情况下，它们可能与传统假设的健康状况无关。特定条件测量和适合度之间的任何关系都应该首先经过经验验证，然后才能将条件用作适合度的代理。在缺乏这样的证据的情况下，研究人员应该明确承认，假设这种关系可能是不现实的。
Mass or body-size measures of ‘condition’ are of central importance to the study of ecology and evolution, and it is often assumed that differences in condition measures are positively and linearly related to fitness. Using examples drawn from ecological studies, we show that indices of condition frequently are unlikely to be related to fitness in a linear fashion. Researchers need to be more explicit in acknowledging the limitations of mass-based condition measures and accept that, under some circumstances, they may not relate to fitness as traditionally assumed. Any relationship between a particular condition measure and fitness should first be empirically validated before condition is used as a proxy for fitness. In the absence of such evidence, researchers should explicitly acknowledge that assuming such a relationship may be unrealistic.
